If it is normal to be grateful to any person who offers you help, then parents are the worthiest of all as they deserve thankfulness and appreciation because of the help, support, and love they show towards their children without even expecting any recompose in return. The happiest moments in a parents' life is when they see their children in the best possible condition and the greatest of positions. Such great parental sacrifices must be rewarded by the children by fulfilling the rights and duties of parents. Some of these rights which are mentioned in the Quran are: Obeying them and fulfilling their requests. Being humble towards them and dealing with them leniently and gently. Lowering one's voice when talking to them. Using the best and most beautiful words when talking to them. Being dutiful to them when they are old and never show dissatisfaction for their requests, however frequent they might be. Invoking Allaah to bestow mercy and forgiveness on them.
